In this program, we are going to share a c program to implement hashing algorithm.
A hashing function is any function that can be used to map data of arbitrary size to fixed-size values. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes.
Hashing algorithms can be pretty useful. However, IT is a really fast industry and this also extends to the hashing algorithms. The values are used to index a fixed-size table called a hash table.
Copy below C program and execute it with c compiler to see the output of the program.
